Diff: Fix missing dependency in generated .dep files

[Warwick Harvey]

I'll commit this once I've tested it.  If anybody sees any problems in the 
mean time, please speak up.


Estimated hours taken: .5

The generated `.dep' file for a program does not declare the dependency of 
the `_init.c' file on the other `.c' files which comprise the program.  This 
means that with parallel makes (or if, for some reason, make chose to build 
its targets in a different order) then make could try to build the `_init.c' 
file before all the `.c' files exist.  This change fixes this.

compiler/modules.m:
	Make the `_init.c' file for a program depend on the `.c' files
	comprising that program.
